Can I detect if the disk supports WAL mode?
Thanks, I will take a look at the tests.

True, but containers kind of work like firewalls where you whitelist any files so the guest can read/write to the host.

So I guess `mmapped` files only work on the same OS.

Linux host and Linux guest seems to work (same Linux kernel instance), but a non-Linux host always results in a corrupt DB (Linux kernel runs in a VM).
